Mayorga has a reputation for trash-talking

Former welterweight world champion Trinidad is returning to the ring after a two-year lay-off.

"Tito's been knocked out ever since he signed that contract his dad put in front of him," said Mayorga.

"First there was Oscar (De la Hoya), then Roy (Jones) then this old rusty can. He's going down," added the outspoken Nicaraguan.

Talking at the pre-fight news conference, Mayorga (27-4, 23 KOs) predicted a ninth-round finish and stamped on a poster carrying Trinidad's image.

Trinidad (41-1, 34 KOs), whose last outing was in May 2002, was visibly riled when he stepped up to the podium.

"I'm well prepared to hit this clown very hard," said the 31-year-old Puerto Rican.

"On Saturday night, when I hit him and he falls down to the canvas he's not going to be acting. It's going to be real."

Trinidad also offered a contract for Mayorga to sign guaranteeing the victor an extra US$100,000 from the loser's purse, although it was unclear whether Mayorga signed it.

"This is real - if you don't accept it you're a real woman," said Trinidad.
